trained up as a small standard shrub, or it may be 

 trimmed to a single stem and head, potted, and placed 

 in the green-house. As extremely low evergreens, we 

 may mention Gualtheria procumbens- and Shallon, 

 Polygala Chamaebuxus, and Astragalus Tragacantha ; 

 but these would probably be better placed among what 

 are popularly called American plants. Of the more 

 tender evergreens, we should name the Andrachne 

 (Arbutus Andrachne), a beautiful shrub, but liable to 

 be injured by severe frosts ; and the pittosporum 

 Tobira of Japan, with glossy foliage and fragrant 

 flowers. The Broad-leaved Myrtle (Myrtus Romana), 

 in warm places, and with the aid of a covering in the 

 depth of winter, may be made to clothe the wall with 

 its brilliant verdure for eight months- in the year, and 

 with its white flowers for some weeks in the end of 

 summer. Treated in the same way, the noble Magnolia 

 grandiflora (particularly the Exmouth variety) will 

 yield its large and fragrant blossoms. Aucuba Japonica 

 and Buxus Balearica are handsome shrubs, of a some- 

 what stronger constitution ; the former is very orna- 

 mental in dull shady places, where no other shrub will 

 grow, and it withstands severe frost, which destroys 

 laurustinus. The beautiful tribes of Cistus and Heli- 

 anthemum, some- of which are quite hardy, are well 

 adapted for adorning sloping banks. 



Amongst the shrubs that require a peaty soil, or at 

 least a damp and shady situation, the splendid genus 

 Rhododendron holds the principal place.. Of the- larger 

 species may be mentioned R. Ponticum, Catawbiense, 

 and Maximum, with their numerous hybrid- varieties. 

 In early spring, R. Dauricura and atrovirens expand 

 their blossoms among the first of flowering shrubs.
